Subject: [lkp-robot] [xfs] 942491c9e6: aim7.jobs-per-min 36.5% improvement
Greeting,
FYI, we noticed a 36.5% improvement of aim7.jobs-per-min due to commit:
commit: 942491c9e6d631c012f3c4ea8e7777b0b02edeab ("xfs: fix AIM7 regression")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: aim7
on test machine: 40 threads Intel(R) Xeon(R) CPU E5-2690 v2 @ 3.00GHz with 384G memory
with following parameters:
disk: 4BRD_12G
md: RAID0
fs: xfs
test: disk_rd
load: 9000
cpufreq_governor: performance
test-description: AIM7 is a traditional UNIX system level benchmark suite which is used to test and measure the performance of multiuser system.
